NTSB is investigating a near miss involving an United Boeing 777

The National Transportation Safety Board (NTSB) (Washington) has launched an investigation after a United Airlines Boeing 777-200 en route from the San Francisco (SFO) hub to Beijing flew about 300 feet under an Aeronca 11AC shortly after takeoff from San Francisco International Airport on March 27.

The NTSB said in a statement the pilots of United Airlines flight UA 889, which was carrying 251 passengers and 17 crew, saw the light high-wing Aeronca shortly after the 777 had taken off and was retracting its landing gear.
